BRUSH-CLEANING DEVICE FOR CARPET-SWEEPERS.

To all whom it may concern:

Be it known that we, Hnunen'r STANLEY Aunou and LEWIS Chink COLLNER, citi- Zens o't thet nited States, residing at St. letcrsburg, in the county of Clarion and State of Pennsylvania, have invented new and useful Improvements in Brush-Cleaning Devices for Carpet-Sweepers, of which the following is a specification.

Our present invention relates to improvements in carpet sweepers of the class involving a rotary brush, and it has for its object to provide a novel and improved device for automatically cleaning the brush of hair or other materials picked up from the floor and which ordinarily have a tendency to mat upon the brush and thereby impair its etiiciency, the cleaning device according to the present invention ope 'ating to automatically remove hair and such other materials from the brush while the latter revolves in passing I over the floor.

,\'lore specifically, the invention consists in providing a brush cleaning devlce which is so constructed that it may be quickly fitled into sweepers already-in use, or it may be supplied as a part of sweepers at the time they are manu'tactured, the securing means tor-the cleaning device serving to ell'ectually hold the device so thatits prongs stand at a proper angle with reference'to the brush, and gripping devices are used which cooperate with opposed walls of the sweeper casing and thereby el't'ectually prevent:- turning or displacement of the cleaning device.

To these and other ends, the invention consists in certain improvements. and combinations and arrangements of parts, allas will be hereinafter more fully described, the novel features being pointed out particularly in the claims at the end of the specification. 7

In the accompanying drawing: Figure 1 represents a transverse section of an ordinary carpet sweepcr equipped with a brush cleaning device constructed in accordance with our .present invention: Big. 2 repre seats a front elevation of the sweeper as shown in Fig. l. the upper portion of the casing beingbroken away to illustrate the cleaning device which is mounted therein; and Fig. 3 is a perspective view of the cleaning device together with the means for Specification ofLetters Patent.

mounting and securing it within the sweeper casin Snmlar parts are designated by the same reference characters in the several views.

In the accompanying drawings, We have shown the cleaning device as applied to a carpet sweeperof the ordinary well known form comprising a casing 1, the front and rear dust-collecting pans 2 and 3, the revo luble bristle brush 4 which is mounted between the pans, and the wheels 5 which roll upon the floor andserve to revolve the brush in opposite directions as the sweeper is be removed from the cleaning device and de posited into one of the dust-collecting pans.

In the accompanying d 'a-wing, the cleaning device comprises a rod 6 which may be composed of wire of an appropriate gage to insure the requisite rigidity, and this rod is approximately of a length corresponding to the width of the space between the two end walls 7 and S of the sweeper casin This rod is provided with a row of depending spurs or forks S) which are spaced about half an inch apart and they are all curved in a direction laterally of the rod.

According to the present invention, the cleaning device is equipped with devices whereby it. may be readily mounted between the end walls of the sweeper, and for this purpose. one end of therod is formed with a pair of spaced prongs 10 which are sharpened so that a longitudinal pressure of the rod will cause these prongs to enter the wood composing one of the end walls of the operated within the casing, and a gripping the rod, this gripping device comprising a mediate portion of which is apertured as at 13 so as to fit loosely over the threaded end of therod 6, and the two edges of the member are provided with rows of sharpened teeth 14. which are adapted to obtain a firm hold against the adjacent end wallof the sweeper casing.

We claim as our invention l.- A brush cleaning device for carpet sweepers comprising a rod having a row of suitably spaced prongs adapted to engage the brush, and means for detachably mounting the device between the side walls of the sweeper casing embodying gripping devices arranged at the opposite ends of said rod, one of said gripping devices having means for moving it longitudinally of the rod.

2. A brush cleaning device for carpet sweepers comprising a rod provided with suitably spaced prongs adapted to clean the brush and having pointed gripping devices .at opposite ends, and means for producing a relative )arating movement between said evices in a direction longitudi- .nally of said rod to cause the gripping degripping vices to engage the inner surfaces of opposed Walls of the sweeper casing and thereby secure the cleaning device therein.

' 3. A brush cleaning device for carpet sweepers comprising a rod having a row of suitably. spaced prongs adapted to engage the brush, one end of the rod being provided with laterally spaced pointed projections to non turnably engage one wall of the sweeper casing, and a gripping device arranged at and movable longitudinally with respect to the opposite end of said rod and provided with means for moving it longitudinally of said rod to force it into gripping engagement with an opposed wall of the sweeper casing. I

4. A brush cleaning device for carpet sweepers comprising a bar provided with a row of suitably.spaced prongs to engage the brush, a gripping device at one end of the bara'da ted to obtain a hold against the in- .ner sur ace of a wall of the swee er casing, andmeans carried by the bar an cooperating with said gripping device for forcing said-gripping device into engagement with the sai inner surface of a wall of the sweeper casing and for maintaining it in such engagement whereby said bar will be 5 supported in operative position. substantially U-shaped member the intero. A brush cleaning device for carpet sweepers comprising a bar provided with a row of suitably spaced prongs to engage the brush, a pair of relatively movable gripping devices at the opposite ends of the bar, and means movable longitudinally on said bar and adapted to move one of said gripping devices for increasing the distance between said gripping devices to cause said devices to obtain a hold upon opposed walls of the sweeper casing.

G. A brush cleaning devcie for carpetsweepers comprising a bar having a row of suitably spaced prongs to clean the'brush, one end of the bar being provided with a pair of pointed prongs and the opposite end of the bar being threaded, a toothed gripping device movable with respect to the threaded end of the'bar and having outturned teeth thereon, and a nut cooperating withthe threaded portion of the bar and with said gripping device and serving to lllOVG' the lattertoward the free end ol'the bar to produce an expansion thereof.

7. The combination of a carpet sweeper having a casing, a revoluble' brush mounted therein, and a device for removing hair, lint and other material from the brush comprising a bar extending longitutilinally between the end walls oiflhe easing above the brush and having a row of suitablyspaced prongs depending from the bar all of said prongs being curved laterally thereof and in the same direction to cause a lifting of the material from the brush when the latter. re volves in one direction and permitting re moval of the material from the prongs when the direction ofrotation of the brush is reversed and devices arranged at the opposite ends of said bar and having means for .expanding them against the inner surfaces of opposed walls of the sweeper casing for securin said bar in position.
